THE MECHANISM OF LASIK
In the procedure of LASIK suction in the range of 60-80 mm hg is created using a suction pump. The intention is to try to flatten the cornea which is normally curved. At the peak of the suction a blade or LASER is used to shape a flap. The laser achieves this by multiple bursts of picosecond laser energy applied ata constant predetermined depth.
The blade may be metal or diamond.
Microkertomes may be Rotational or Transitional
CUSTOMAIZATION OF THE LASIK FLAP
1. Ring Size The larger ring size leads to a larger flap. It also leads to thinner flaps
2. The stop Controls where the blade stops its motion thus determining the size of the hinge
3. The speed of the oscillating blade. The faster it moves the thinner the flap will be
